Kennys lawn is 30 feet wide and 30 feet long. It takes him 1 hour to mow the lawn. If kenny mows at the same rate, about how many hours would it take him to mow a lawn that was 30 feet and 95 feet long?

30 * 30 = 900 square feet in one hour
30 * 95 = 2850 square feet
2850 / 900 = _______ hours 
area of the 30by30 lawn = 900 ft^2
so he can mow 900 ft^2/hr
larger lawn has area of 2850 ft^2
time = 2850/900 hrs
= 3.166667 hrs
= 3 hours and 10 minutes 
So confused I'm in 5th grade and my answer was 3hrs and 30 mins. Explain simple for me

2850/900 = 3 1/6
so that is 3 hours + 1/6 of an hour
1 hour = 60 minutes, so 1/6 of 60 = 10
(because 6x10 = 60)
